Abstract

Eighteen adults with night vision complaints showed significantly increased/final rod thresholds as compared to their age- and sex-matched controls. Vitamin A and zinc levels did not differ between the two groups. Vitamin A supplementation of three subjects produced changes in final rod thresholds and serum vitamin A levels. These changes did not produce subjective improvements in night vision.
